Into The Hollow

This is a Sci-fi project I have been working on my spare time created in Substance Designer and Zbrush sculpted height maps to create a hybrid procedural substance material. I took the name from a song called "Into The Hollow" by Queens of the Stone Age which I was influenced to make this piece.
I did not use reference, this was to be a fun experiment to see what art would come out of my head and what came out was a derelict abandoned tunnel vibe resembling the movie aliens but less organic and more industrial.
